Complete Blood Picture (or) Cbp test is part of a routine screening test, when there are signs and symptoms that are related to a conditions which affects blood cells like RBCs, WBCs or platelets and to monitor the effectiveness of treatment.
1. What other tests are useful in case if CBP is abnormal?
when WBC is abnormal, tests like ESR, C reactive protein, blood culture, urine culture and sputum culture are useful if suspecting infections, and bone marrow studies, immunophenotyping may be needed in leukemias, myelodysplasia etc.
Abnormal RBC results may need additional test like reticulocyte count, iron studies, serum vitamin B12 and serum folate, or Hb electrophoresis in suspecting hemoglobinopathies.
Abnormal platelet counts may need additional tests like Immature Platelet Fraction, platelet function tests and coagulation tests.
2. What is Immature Platelet Fraction (IPF)?
Platelets are produced in the bone marrow and only after they mature, platelets are released in to the blood. When there is decreased platelet count in the blood, the immature or the reticulated platelets are released into blood before complete maturation and IPF is defined as the relative number of immature platelets in the blood. IPF is useful in determine the cause of a thrombocytopenia. The thrombocytopenia can be due to decreased production of platelets by bone marrow (where IPF is low) or due to increased destruction of platelets (where IPF is high).
3. What are immature granulocytes (IG) or what does a shift to left means?
White blood cells are produced in the bone marrow and only after they mature, are released in to the blood. Immature granulocytes are the white blood cells that are not developed completely and released into the blood. Presence of these cells in the blood is called as a shift to the left. They include metamyelocytes, myelocytes, promyelocytes etc. These are seen in conditions like infections, blood cancer etc.
